One of the most difficult things about trying to work out at home [1] when you live in a flat is finding a way not to annoy your downstairs neighbours [2]. (If you live on the ground floor, consider yourself lucky!) Every time I attempt cardio in my third-floor living room, I worry that it sounds like I'm gonna bust through the floor, mostly because every time my upstairs neighbour moves around, it sounds like she's gonna bust through my ceiling. This quick HIIT workout [3] from Maddie Lymburner solves that problem for all of us apartment dwellers.

In just 10 minutes [4] and with no extra equipment, you can get in a great workout while making virtually no noise at all. The no-jumping HIIT workout has a series of intervals, and with it taking so little time, you can fit it into your day pretty easily. Lymburner recommends starting the sweat session with a quick warmup and ending with a cooldown as well, and all of it can be done without bothering your neighbours. Check out her YouTube channel for even more flat-friendly workouts, including full body and abs. You just need a little bit of space to spread out, and you're good to go.
